Make backlight adjustment work in Ubuntu on the Panasonic CF-R7

I was struggeling with the backlight quite for a while now. But finally I found something which finally works.

First you need git core installed

sudo aptitude install git-core

Next you checkout the module

git clone git://

The next step is compiling and loading the module

cd ./pana_acpi
make install
modprobe panasonic_acpi

At this point you can already check if the brightness buttons are working.
Next copy ./pana_acpi/acpi/* to /etc/acpi
and restart the acpid daemon.

/etc/init.d/acpid restart

This module should work on all the 7-Series from Panasonic. I only tried it out with my CF-R7.

Playing with Nokia Sportstracker

I was quite surprised that the N95 built in GPS also worked inside the train. Since I am abroad I switched off assisted GPS and Network help. The device obviously worked quite well anyway. Just check out my route here. It show the way from a bit before Nagoya to Kyoto on the Shinkansen.

In Ubuntu nearly everything works out of the box:

SDHC: works out of the box (never worked for me on the r3)

Hotkeys: Recognized by Gnome but are not working (need to try to find a fix)

Displaybrightness: Doesn’t work at all. Tried pcc_acpi driver on kernel  2.6.22 and 2.6.24 without any luck. Both are also not working with xbacklight.

Suspend to Ram: works out of the box

Frequency Management: works out of the box
